Loading speed is excellent. I agree with gerogeweballey13 that your animations are pretty nice. However, even though I am a huge proponent of simple designs, I think this is actually too simple. There is also far too much consistency. Like most of the pages it just alternates from text on left to text on right of picture. I think it has a little too much of a tacky feel to it. I really like your navigation bar a lot though. Excellent hover effects and great mobile friendliness. Logo is good, but not great.

I like the basic design and layout of your site. I am a firm believer in the KISS system (Keep It Simple Stupid). Too many website these days are so busy that it is hard to focus on anything in particular. In looking at your different pages, I think there is way to much white space between subject matter. In my personal opinion, it is spaced out a bit much for my liking.

Your Website is Great, it loads really fast and the overall view looks good, as I saw you support the website in bulgarian language, So I suggest you to create a language selection drop down menu and add your language selection space on the right corner.
